new problem

ok we found out that we are not getting gas all the way through the engine. as long as we keep sprayin starter fluid or carburater cleaner into the manifold, it will keep turning over. but when we stop spraying, the car goes rite bak to tryin to start again. the injectors are not clogged. they are brand new stock injectors. so that means they dont have to be timed. that cancels that out. we are getting fuel to the motor, its just not goin through it


i have a 91 N/A stock. i bought this car from a friend down the street a while bak. ive been doing my best to replace needed parts. i have replaced fuel injectors, fuel pump, fuel filter, battery, battery terminals, starter, fuel lines, etc.

the car will just keep tryin to start when i turn the key. somethin is keeping it from fully turning over. every now and then it halfway turns over but it just quits tryin immediately. ive got plenty of power. just give some ideas or somethin.

Turning over = cranking
Think you mean running... something is keeping it from running...

and your descriptions suck. Is the starter not turning, is the starter staying on???

So, the car cranks over ... yes? no?
Is the starter staying cranking, even after you have turned the key off? yes No?
When the car cranks over, does it start running? Yes? No?

And you are saying that you replaced the fuel injectors, the fuel pump, the fuel filter, the batter and terminals, the starter and the fuel lines...

That is a lot of things changed. Were they all bad or what???

And is your AFM and intake all tubing connected and in place? Because if you are spraying carb cleaner or starting fluid at the manifold, then you don't have them hooked up... and they need to be hooked up for the engine to run.

Change your Soft fuel lines inbetween the fuel filter and the engine.(Flip them..one is Intake:goe TO the primary Injectors, the other is Residual:Excess fuel goes back into the Tank.).I have a feeling you may have got those mixed up

ok i changed my fuel lines and did wut u guys said. i thought for a while about that to. still nothin. im pretty sure they r in the rite place. i looked in the haynes manual.

no car does not crank over. thats the problem. i dont even no if it will stay running. only thing is when u turn the key the starter turns the motor. nothing else. i was told i didnt have combustion but i have compression

So the starter is cranking over, it is just not starting and running?

Or the starter is not cranking?

Intersting im having the same problem in my second gen as well pm when u figure something out but first thing is first get a multi meter to check the resistance on the primary injectors to see if the injectors are even turning on.Cause u say u spray eather and it turns on until the eather is burned off then shuts off. Im thinking maybe a faulty ecu is ur problem but check that out first.If the car is turning on the injector but not spraying enough fuel then t off the fuel line and check fuel pressure to factory specs in ur haynes manual !!!!

and you really threw away all that money and replaced everything that you said you did in the first post in this thread?

What condition are the spark plugs (and don't just say that you replaced them... I am asking you what are there condition this very second) are they wet, are they dry? are they all black with oil??? what condition are they in?

Okay, if you go to the fuel pump diagnostic plug (yellow passengers strut tower area) and jumper the two pins together, turn the key to ON, do you hear fuel running through the rails???
